here are some common factors that are typically considered:
Age: ReLEx SMILE is generally performed on individuals who are at least 18 years old. This is because the eyes are typically fully developed by this age.
Stable Refractive Error: The candidate's prescription should have remained stable for at least one year. This means that their eyeglass or contact lens prescription should not have significantly changed during that period.
Myopia (Nearsightedness): ReLEx SMILE is primarily intended for the correction of myopia. Candidates should have a certain range of myopia, usually up to -10 diopters or more depending on the surgeon's expertise and equipment.
Astigmatism: Depending on the surgeon's experience and the technology available, ReLEx SMILE may also be suitable for individuals with astigmatism up to a certain limit, typically around -5 diopters or less.
General Eye Health: Candidates must have healthy eyes, free from any eye diseases such as glaucoma, cataracts, corneal diseases, or severe dry eye syndrome. They should also have a sufficiently thick cornea to accommodate the laser treatment.
Overall Health: The candidate should be in good overall health to ensure proper healing and recovery after the surgery. Certain medical conditions or medications may affect the suitability of the procedure, so it is important to inform the surgeon about any pre-existing health conditions or medications being taken.
